Allium hollandicum 'Purple Sensation'

allium or Dutch garlic bulbs

Product Image
Allium hollandicum 'Purple Sensation' is probably one of the most popular of all the alliums. They have a striking silhouette which makes them particularly well suited to gravel or prairie-style planting schemes, but they also look fab in pots or mixed borders.

Their densely packed umbels of deep violet, star-shaped flowers appear in early summer above strap-shaped grey-green leaves (which will have already started to die off by the time the blooms form). Therefore, they team up well then with things like herbaceous geraniums or ornamental grasses, which will help mask these leaves as they die off.

How to care for Allium hollandicum Purple Sensation:

Allium bulbs are easy to grow in a sunny spot with freely drained soil, or a good quality potting compost. Ideally they should be planted in September or October, but could also be planted in early November in milder regions.

While keeping the size of the flowerhead in mind and avoiding overcrowding, dig holes roughly three times as deep as the diameter of the bulb and place them at the base, pointy side up before gently infilling and watering to settle them in.

In early spring, as growth begins, apply a balanced, slow-release fertiliser, and allow the plants to die back naturally and completely before tidying away.
